Application May 3, 1944, Serial No. 533,921

This invention relates more particularly to a system or means for regulating or justifying the spacing of printing character images in apparatus of the nature disclosed in U. S. Patent #2,180,41'7, granted to me Nov. 21, 1939, for Apparatus for photographically composing printing or type characters. However, the justification or regulating means of this application are also applicable to other .more or less analogous uses, and the claims of this application are intended to comprehend such other uses except where the contrary is clearly manifest from their language.

The apparatus disclosed in said patent comprises a font or set of printing or type characters including the upper and lower case letters, numerals, punctuation marks and various other signs or characters necessary for composing printed matter; optical projecting devices for se-- lectively projecting images of such printing characters for exposure in a required relation on the sensitized or light-sensitive surface, or coating of a plate or other medium, and means for moving said sensitized surface to present successive portions thereof in position to receive the successively projected images of the selected printing characters so as to thereby photographically compose matter on a surface for use in producing printed or reading matter.

One object of this invention is to provide a practical and eiilcient system or means for accurately regulating the locations or spacing of and/or justification of successive positions of a thing or things; and more specifically to provide such a space regulating or justifying means for the images of the printing characters in apparatus oi the nature disclosed in said patent for photographically composing printing characters.

Heretofore justification means have been employed in hot metal casting machines, such as Linotype. Monotype, Intertype and other apparatus. Also, attempts have been made to justify the printing lines in so-called phototypesetting machines, but with variable and more or less unsatisfactor results. Another object of this invention is to provide a practical justificati n system which is simple and easy to operate and will be accurate in its operation and in its control of the character and space position justification as predetermined by the operator, whereby an appropriate keyboard may be operated to select required characters to compose reading matter, and to divide the words or matter by suitable spaces, all of which ar to make up the matter in lines of required or desired length as interpreted by standard type gages for type point size and agate lines.

Another object of the invention is to provide a justification system or means so designed that printing characters of all type point sizes, say from 4 point to 80 point and over, can be quickly 23 Claims. (Cl. 95-45) composed or set so that the image thereof exposed or recorded upon a sensitized surface will be automatically predetermined or figured with the proper spacing of the characters and words so that the exact, required length of line can be attained, either by spreading of the characters and spaces, and within reasonable limits, by condensing the line or crowding the characters and reducing the spaces to attain the exact needed length of the printed line. Obviously, when condensing the line length, the operator must use judgment in not crowding the characters unreasonably, this point, however, being optional, since the means provided -for condensing the line permits the actual touching 01' characters, so that, for instance, script letters may be joined as a continuance line. i

Other objects of the invention are to permit instant proper character spacing and lengthening or shortening of the line length in relation to the point size of the characters being composed before the photographic recording thereof on the sensitized surface; and also to provide simple means for accomplishing this result for various different point sizes of characters. This latter object may be accomplished, as disclosed in this application, by providing a plurality (say three, for example), of interchangeable justification bars or devices, each for use with a different group of character point sizes, as for instance, one for characters from 4 to 14 point sizes inclusive, a second for characters from 15 to 26 point sizes, and a third for characters from 27 to 36 point sizes; the justification bar Or device for one group of character sizes being mounted in the appara tus so that it can be quickly and easily removed and replaced by an interchangeable justiflcation bar or device for a different group of character sizes.

Still another object of the invention is to produce justiflcation means which provide for standard or regular character spacing which may be increased or decreased uniformly or proportionately for a number of characters; and which can be readily adjusted at will, to change the spaces needed to accommodate the width of certain articular characters, such for example as the letters M or W, which require wider spaces than normal, and the letter I which requires a narrower space than normal.

Further objects and advantages of the invention will appear from the following specification of the preferred embodiment of the invention shown in the accompanying drawings, and the novel features of the invention are set forth in the appended claims.

In said drawings: v

18. 7 is a plan view thereof, broken to show parts which lie in different planes.

Fig. 8 is a broken plan view of the supporting bar or member for the justification bar or device.

The justification apparatus illustrated in the drawings as a preferred embodiment of m invention comprises an open, rectangular upright or vertical main frame or support A for the justifying mechanism, an open rectangular frame B which is fixed on and extends horizontally or perpendicularly to the plane of the main frame A and forms a guide bed for a movable carriage C which supports the sensitized surface, shown at D. This sensitized surface, which may be formed by a plate, film or other suitable medium having a light-sensitive surface or coating, is supported by the carriage in a vertical plane extending in the direction of movement of the carriage C on its guide frame B.

In this application this sensitized surface is illustrated and hereinafter sometimes designated as a sensitized pla which is arranged to move in its own plane in one direction, as horizontally with its supporting carriage, for exposing successive character images on the plate in a horizontal line across the same, and also to be adjusted on its carriage vertically in its plane, for exposing the character images in successive lines one below the other on the plate. But it is to be understood that it is not intended to limit the invention to use with a sensitized plate, since the sensitized surface can'be either on a rigid plate or on a flexible film or other suitable medium. and the sensitized surface may be mounted and moved vertically in any suitable manner for effecting said different adjustments thereof, for example, as shown in said patent, which discloses means for mounting and moving both a sensitized plate and a sensitized flexible film which is moved vertically for successive line exposures by appropriate operation of rolls that carry the film. Only such parts of the photographic composing apparatus are disclosed herein as are necessary to a proper understanding of this invention, it being understood, however, that the justification means or mechanism of this application are associated or coordinated with parts of a photocomposing apparatus or camera such as shown in the patent before mentioned, and in my U S, Patent #2,289,l21 for a Universal camera, issued July 7, 1942, as may be necessary to provide for the support and intended operation of the controls and other parts of the space-regulating or justiflcation means forming the subject-matter of this application, and as may be required to provide enclosure for all of the devices or parts whereby the sensitized surface may be affected only by the light action necessary for recording images of the intended subjects or printing characters on the sensitized surface.

Oil

The carriage C, as shown, comprises a rectangular horizontal base frame E, the longitudinal side bars Ill of which are furnished with supporting rollers ii adapted to roll on the parallel side bars i2 of the guide frame 13. the carriage being suitably guided thereon in its longitudinal travel as by guide rollers i3 and I4 on the carriage arranged to roll in contact with opposite sides of one of the side bars i2 of the guide frame. The carriage is thus adapted to travel horizontally on the guide frame B in the direction of the vertical plane of the sensitized surface. This horizontal travel of the carriage may be effected by suitable propulsion means, such as a shaft i5, provided at opposite end portions with pinions I. meshing with toothed racks I! on the side bars I2 of the guide frame B. The shaft l5 may be turned manually, as by a crank ill at one end thereof, and an electric motor I9 is also shown which preferably is suitably geared to the shaft l5 as by slip or friction operated gearing 2|! for propelling the carriage. This slip or friction gearing permits the step-by-step advance movements of the carriage. presently described, and also enables the carriage to be moved manually if desired.

The sensitized plate is suitably supported in a vertical plane on the carriage C, for which purpose the carriage is shown as made with an upright, open frame portion having spaced side bars 2| between which the sensitized plate is located and suitably supported for vertical adjustment on the carriage. Means conventionally illustrated for this purpose comprise a carrying frame which has horizontal bars 22 provided with suitable clips 23 for holding plates of different sizes and may be adjusted vertically on the carriage for exposing images of the printing characters in lines one below another on the plate, as by vertical adjusting screws 24. My said patent No. 2,180,417 more fully discloses suitable means for mounting and vertically adjusting on the carriage either a sensitized plate or a sensitized flexible film of required length carried by winding rolls.

As before explained. the sensitized surface may be provided on a plate, film or other suitable medium and any known or suitable means may be employed for mounting and adjusting the sensitized surface to enable the images of the printing characters to be exposed or recorded on the surface in horizontal lines spaced one below another.

A horizontal disk or support 25 is rotatably supported by the main frame A below the sensitized plate carriage. Preferably, this is a circular disk mounted by a central pin 26, about the axis of which the disk is horizontally rotatable, on an adjusting bar 21 which in turn is slidably supported and adjustable lengthwise of itself on the bottom bar of the main frame A, An adjusting screw 28 is shown suitably journalled and held from endwise movement on the main frame A and having a screw threaded connection with the supporting bar 21 for moving the latter lengthwise to adjust the disk 25 bodily in a direction parallel with the vertical plane of the sensitized plate, the axis of the disk being preferably located below and in the vertical plane of the sensitized surface. A crank handle 29 is shown for turning the screw to thus adjust the disk, but it is intended, as hereinafter explained, to effect this adjustment of the supporting bar 21 and the disk 25 either by suitable automatically or manually operated means, automatic adjusting means for the purpose being disclosed in a copending application.

Mounted upon and preferably extending diametrically across the top of the rotatable disk 25 and removably supported in a channel formed by two parallel spaced guide bars 30 secured in a shallow, diametrical groove 3| in the top of disk 25, is a bar or device 32, herein designated the justification bar. As shown, this bar is formed of upper and lower sections and supports a series or row of spaced carriage stop elements 33 arranged to move up and down on the justification bar. The stop elements 33 are shown as pins movable endwise in vertical guide holes in the upper section of the justiiication bar to and from a position in which they project above the bar into the path of movement of a cooperating stop bar or member 34 secured on the supporting carriage C for the sensitized plate. Stop bar 34 extends across the bottom of carriage C in a plane at right angles to the plane of the sensitized plate thereon and is adapted to engage one after another of the pins 33 which are retracted in succession as presently explained, for effecting a step by step movement of carriage C. As best shown, see Figs. 5 and "l, the lower portions of the stop pins 33 extend through a lengthwise channel in the lower section of the justification bar 32 between two flexible ribbons or hands 36 which extend lengthwise in said channel at opposite sides of the row of stop pins. These ribbons, which may be transversely corrugated and bear against the opposite sides of the pins 33, are held under lengthwise tension in the justification bar so that they press against opposite sides of the several stop pins in a manner to frictionally hold the stop pins either in their projected position in the path of movement of the carriage stop 34, or in a retracted or depressed position in which the carriage stop 34 is adapted to pass over the upper ends of the pins, clear thereof.

Movable up and down, or toward and from the justification bar, on the sensitized plate carriage C, is a retracting bar or member 31 for engaging and depressing or retracting the stop pins 33 one after another. As shown, this retracting bar is provided with a relatively thin bottom flange 31a adapted to engage the tops of the stop pins and has one or more downwardly opening recesses confining one or more springs that tend to lift or counterbalance the weight of the retracting bar, one of such springs being shown at 38, Fig. 5. As shown, a guide channel for the retracting bar is formed between parallel, spaced transverse bars 39 at the bottom of carriage C and the carriage stop bar '34 extends across the bottom of this channel to the bottom flange 31a of the retracting bar, which flange extends down between the adjacent guide bar 39 and the front edge of the carriage stop bar 34, the lifting springs 38 for the retracting bar hearing at their lower ends on the stop bar, which is stationarily secured on the carriage.

In the normal or rest position of the parts, the several stop pins 33 will be in their upper raised orprojected position, as shown by the pins at the right in Fig. 5, and the carriage stop 34 will engage the projecting upper portion of the first pin, or pin at the left end of the seriespf pins. as seen in Fig. 5, thereby preventing forward movement of the carriage, or to the right, as seen in said Fig. 5, and the bottom flange of the retracting bar 31 will be directly over the top of the stop pin which the carriage stop engages. If then the retracting bar is depressed, this pin 6 will be depressed or retracted out or the path of the carriage stop and the carriage C will be moved forwardly by its motor l9, until arrested by engagement of the carria e stop with the second a pin 33, the retracting bar, of course, having been returned to its normal raised position, shown in Fig. 5; to permit engagement of the carriage stop bar with the second stop pin. The carriage C is thus advanced step-by-step by retracting the stop pins 33 in succession in this manner, the length of each step movement being determined by the spacing or distance apart of the sto pins in the direction of travel of the carriage.

The mechanism shown for operating the retracting bar 31 to eiIect this step-by-step advance movement of the sensitized plate carriage comprises toothed racks 40 secured to opposite ends of the retracting bar and meshing with pinions 4| on the opposite ends of a shaft 42 suitably journalled on the carriage C parallel with the retracting bar. Also meshing with the pinions 4| are toothed racks 43, each of which is connected with an operating motor, preferably a pneumatic or fluid pressure-actuated motor 44,

of any suitable construction. The motors 44 shown are suitably mounted on th carriage C at opposite ends of the guide for the retracting bar, and fluid under pressure is supplied to them as through supply pipes 45, see Fig. 1. Preferably, each of these motors is operated by a valve 46 under the control of an electromagnetic control device indicated conventionally at 41. This mechanism is such that when the control magnets are energized, as by the actuation of a contact device, as explained in my copending application, Serial No. 533,920, for Relay character selecting means, air or fluid under pressure will be admitted to the motors 44, which will move the racks 43, pinions 4| and racks 40 in the direction to push the retracting bar 31 downwardly and retract the stop pin 33 which it engages, thereby causing the carriage C to advance one step. Then, said contact device operates to deenergize said magnets, thus permitting the motor valves 46 to be shifted by suitable springs 48 to cause reverse actional of the motors 44 to return the retracting bar 31 to its normal, raised position. The electrically controlled motors 44, above briefly described, are illustrated and described in detail in my copending application, Serial No. 537,236. However, controlled motors or means of other suitable construction could be employed for actuating the bar or member 31 for retracting the carriage stop elements 33.

Arranged. parallel with the justification bar 32 and extending under the several stop pins 33 is a pin-lifting or setting bar or member 50. This setting bar, as shown, is movable vertically in a guide channel in the supporting bar 30 for the justification bar and extends lengthwise under the lower ends of the several stop pins 33 when they are in their retracted position, so that by raising the setting bar 50, all of the pins which have been retracted to effect the step-by-step movement of the carriage will be returned to their normal positions in which they project above the justification bar into the p th of movement of the carriage stop 34. A spring 5| shown in a recess in the lifting bar tends to lift or counterbalance the weight of this bar. Any required number of these springs may be employed.

After the described step-by-step advance of the carriage for moving the sensitized plate the required distance, depending upon the length of the line of printing character images to be recorded thereon, the carriage is returned to its initial position and the several stop pins 33 are returned to their normal projected position by raising the lifting bar 50, which is then again returned to, its normal, lowered position so that the step-by-step advance of the carriage can be repeated for recording the next line of character images on the sensitized surface.

Preferably, the means for thus operating the pin setting bar 50 are similar to the operating means for the retracting bar 31, and may be described as follows:

Toothed racks 53 are secured on opposite ends of the lifting bar 50 adjacent the ends of the justification bar 32 and mesh with pinions 54' suitably journalled on the ends of the guide for the justification bar. Also meshing with pinions 54 are toothed racks 55 which are connected with operating motors 56 which may be fluid pressure-actuated motors, like the motors 44 for the retracting bar, and controlled by electromagnets 51, in turn controlled by a suitable finger key. For example, when this key is depressed, the magnets operate the motor valves to cause the motors to act through the racks 55, pinion 54 and racks 53 to raise the pinion setting bar and lift the stop pins 33 to their normal projected position, the operation of the motor being reversed and the lifting bar returned to its normal position upon the release of the control key.

It will be noted that the operating motors 55 and magnets 51 for the stop pin setting iar are constructed and shaped so that they can be mounted on the justification bar guide or support, and extend to one side therefrom, but will not project above the top and bottom planes or the justification bar and its support, and the operating motors and magnets for the retracting bar are similarly proportioned and mounted with ref erence to the guide or support for the retracting bar, so that these motors and control elements will not interfere with the movement of the carriage stop bar past the justification bar and its stop elements, or with the hereinafter explained adjustment of the justification bar beneath and to different angular relations with respect to the carriage stop and the direction of travel of the carriage.

As above mentioned, the disk 25 is rotatable about its axis and since the justification bar 32 is mounted on this disk, it can be adjusted from a position shown in Fig. 5 in which its row of stop pins parallels the direction of movement of the sensitized plate carriage, to different positions at a greater or less obliquity or angularity to said direction of movement of the carriage and the carriage stop 34. When the row of stop pins ll parallels the direction of travel of the carriage, the length of the step movements of the carriage, which is determined by engagement of the carriage stop I with successive stop pins, will equal the actual linear distance between successive stop pins, whereas if the justification bar is adjusted to set the row of stop pins at an angle to the direction of carriage travel, the distance which the carriage stop moves from engagement with one pin to engagement with the next pin will be less than the actual linear distance between the pins, and this distance will decrease in proportion as the line of the stop pins is adjusted to greater angularity from the direction of travel of the carriage towards a line at right angles thereto. For instance, the maximum length of the carriage step movements is indicated by the distance between the broken lines :2

8 projected from the stop pins in the right-hand position of Fig. 1, when the row of pins parallels direction of travel of the carriage, and a lesser length of the step movements is indicated by the distance between the broken lines y projected from the stop pins, in an oblique adjustment of the row of stop pins, as shown in the left-hand portion of Fig. 1. The stop pins are uniformly spaced on the justification bar and, manifestly, the decrease or increase in the length of step movements of the carriage effected by such angular adjustments of the justification bar will be uniform or proportional to the spacing of the stop pins throughout the whole series of pins.

The means shown in the drawings for effecting angular adjustment of the justification bar comprises a radial arm 80 projecting from disk 25 and having a pin and slot connection 61 with an adjusting bar 62 which is movably mounted on the supporting frame and adjusted lengthwise, as by rack and pinion mechanism 53. This angular adjustment can be effected by manual operation of this adjusting means, but automatically controlled mechanism for the purpose may be employed, as is disclosed in a copending application for patent, whereby it is possible for the operator, when operating the composing apparatus for selecting the printing characters for projection onto the sensitized surface, to predetermine the required spacing of the characters and the length of the line of printing, depending upon the point size of the printing characters, by appropriate setting of suitable control means, and the justification bar will be automatically adjusted by the control means in accordance with such predetermined setting thereof by the operator.

In addition to this justification adjustment for the whole printing line, the disk 25 and justification bar can be shifted or adjusted bodily in the direction of travel of the carriage and sensitized surface by means of the adjusting member 29, as before explained, when this is necessary to provide for the spacing of special characters, such as the letters M, W and I, which require more or less than the normal spacing.

It will thus be noted that the herein disclosed means for justifying the printed line comprises a series or row of spaced stop elements which control the step movements of the sensitized surface for recording successive printing characters in proper spaced relation in a line thereon, and uniform variation in the length of the spaces between printing characters in the line is determined by changing the angular relationship of this row of spaced stops to the direction of travel of the carrier for the sensitized surface. Also, that in addition to this adjustment, the series of spaced stop element is adjustable as a whole in the direction of travel of the sensitized surface when this is required for a greater or less space for particular printing characters.

It should be further noted that the justification bar or member carrying the row of spaced stop elements may be removably mounted in the apparatus in any suitable manner so that it can be quickly and easily replaced by another justiflcation member in which the elements are differently spaced, to thus enable one justification member to accomplish the line or character and space justification for one range of character point sizes and another justification member to be utilized for a different range of character point sizes.

As disclosed in this application, the spaced 9 stop elements for effecting this variable step movement of the sensitized surface for justification purposespare illustrated in the form of retractable pins on the adjustable justiflcation bar. However, my invention is not restricted to the particular construction and operation of the parts illustrated and specifically described herein, but comprehends means of analogous organization and operation adapted to accomplish similar results.
